Definitions
- the present invention it is possible to localize the sound images of the surround signals at two different rear positions apart from the two front positions at which a pair of speakers are arranged, on the basis of the sound signals reproduced through speakers.
- the present invention also provides a listener with a feeling of presence as if he is listening to the music in a different sound field such as a spacious concert hall, church or stadium notwithstanding the fact that he is actually in an ordinary room, a listening room, or a vehicle
- FIG. 3 is a block diagram for showing a configuration of a surround signal processing apparatus according to an embodiment of the present invention
- FIG. 3 shows a configuration of a surround signal processing apparatus 30 according to an embodiment of the present invention.
- the surround signal processing apparatus 30 includes left and right impulse measuring sections 302 and 304, left and right convolution operators 306 and 308, and left and right reverberators 310 and 312.
- FIG. 4 shows a method of measuring left and right impulses of a head related transfer function in a three dimensional space by the right and left impulse measuring sections shown in FIG. 3.
- the left and right convolution operators 306 and 308 convolve left and right side channel signals L and R of the input audio signal u(m) with the left and right impulses Ij ( ⁇ ll ⁇ . , m) and h R (0 1# ⁇ D , m) of the head related transfer function from the left and right impulse measuring sections 302 and 304, respectively, in order to localize a sound image for the input audio signal u (m) at an objective localization position in the three dimensional space 402.
- the outputs O h ( ⁇ ll ⁇ 3 , m) and 0 R ( ⁇ 1 , ⁇ - , m) of left and right convolution operators 306 and 308 are defined as follows:
- the left and right reverberators 310 and 312 impart first and second reverberant sounds to the left and right channel signals L and R of the input audio signal u(m) from the left and right convolutions operators 306 and 308, respectively.
- the outputs R L and R L of the left and right reverberators 310 and 312 are O h ( ⁇ x , ⁇ D , m)+gl+g2-z ' 3 + g+z and 0 ⁇ 0,, ⁇ , m) +gl+g2 -z ' 3 + 1+g'Z 1
